Required

The Building Division "accepts applications for new, additions, alterations, and repair construction," reviewed and inspected against "the editions of the 2021 International Codes." Applications and supporting documents are emailed to [email protected]; the joint Winter Park/Fraser/Granby building permit application requires the contractor's mailing address, email, phone number, and Business License Number. Inspections are scheduled online and must be requested "by 4 p.m. to receive your inspection the next business day," with the Building Permit number and type(s) of inspection ready at time of scheduling. No page reviewed states explicitly that a permit is required specifically for roof replacement, so that boolean is left unset here; residents/contractors should confirm reroof-permit scope directly with the Building Division.

The Winter Park/Fraser Building Division's page states: "We review plans and perform inspections of all work for compliance with the editions of the 2021 International Codes," and further: "An updated Colorado Wildfire Resiliency Code was adopted on July 1, 2025, and new requirements take effect on July 1, 2026." (Statewide, the Colorado Wildfire Resiliency Code sets structure-hardening standards for wildland-urban interface areas, including Class A roofing requirements for new construction and for re-roof/re-siding work affecting 25% or more of a structure; per the joint building department's neighboring Fraser jurisdiction, Ordinance No. 533, Series 2026 adopts the CWRC 2025 edition effective July 1, 2026 for that shared department's territory.)

Required — Winter Park amends the drip edge provision to read: "A drip edge shall be provided at eave and rake edges of all pitched roofs. Adjacent segments of the drip edge shall be lapped not less than one (1) inch. The vertical leg of the drip edge shall be not less than one (1) inch in width and shall extend below sheathing and facia juncture no less than one-fourth inch. The drip edge shall also extend back on the roof deck not less than two (2) inches." About drip edge

Required — Required, and the Town states the requirement directly in its own amendments rather than through a table cell. Winter Park sits at roughly 9,000 feet and its amended ice barrier provision governs, alongside a separate local requirement that valley lining be fully adhered to the substrate for twenty-four inches from the valley centre line on all habitable structures, with an exception only for detached accessory structures containing no conditioned floor area. About ice & water barrier

Not required — The Town of Winter Park's Town Code, Title 6, Chapter 1, Building Codes, was read in full. Section 6-1-1 adopts by reference the 2021 editions of the International Building, Residential, Plumbing, Mechanical, Fuel Gas, Energy Conservation, Fire and Existing Building Codes, the 2020 National Electrical Code and the 2023 Colorado Electric Ready and Solar Ready Code, and Sections 6-1-2 through 6-1-12 carry the Town's amendments to each. The roofing amendments are extensive and were read in full. On the Building Code side, Section 1507.1.1 is amended so that an ice barrier of approved self-adhering polymer modified bitumen is used in lieu of normal underlayment on all sloped roofs, with double underlayment below a 4:12 pitch and a base layer covering one hundred percent of the roof surface; Section 1503.6 and the parallel provisions at Sections 1507.2.8.2.2, 1507.5.4.1, 1507.6.4.1, 1507.7.4.1, 1507.8.4.1 and 1507.9.4.1 require roofs to be designed to prevent snow from shedding; and Section 1503.7 requires each roof valley to have access to an electrical receptacle. On the Residential Code side, Section R905.1.2 carries the same whole-roof ice barrier, Section R905.1.3 the snow-shed requirement, Section R905.10.5.1 mechanical barriers for metal roof shingles and panels, and Section R907.3 requires that new roof coverings not be installed without first removing all existing layers where the existing roof is water-soaked or deteriorated, where the existing covering is wood shake, slate, clay, cement or asbestos-cement tile, or where more than one application is already in place. Every one of those provisions governs underlayment, snow shedding, valley access or tear-off; none classifies the covering material. Neither the adopted codes nor any Town amendment requires impact- resistant roof coverings or names a UL 2218 or Class 4 standard. The only statewide instrument reaching reroofing is the Colorado Wildfire Resiliency Code, 8 CCR 1507-39, effective July 1, 2026 in areas designated wildland-urban interface under that code, which requires a Class A roof covering tested to ASTM E108 or UL 790 where 25 percent or more of the roof surface is replaced, at Sections 101.6 and 403.2; that is a fire classification independent of impact rating, and the code sets no impact-resistance requirement.

No size or value threshold exempts a roof repair. The Town of Winter Park replaces the permit-exemption lists of its adopted building and residential codes in full, and neither replacement list carries a roofing carve-out of any size, so the permit requirement attaches to roof repair work regardless of area.

A design wind speed of 105 mph in Seismic Design Category B. Winter Park amends the climatic and geographic design criteria table to read that "WIND SPEED IS ONE HUNDRED AND FIVE (105) mph with exposure category determined by Section 1609.4", with weathering probability severe, a frost line depth of thirty inches below finished grade, termite and decay probability none to slight, a winter design temperature of minus 16 degrees Fahrenheit and a mean average temperature of 40 degrees. Roof snow load is not given as a single figure: the Town directs that a licensed Colorado design professional may design using ground snow loads from the Structural Engineers Association of Colorado report and map, and notes that changing to roofing materials other than like materials may require a roof evaluation by a licensed Colorado engineer.

One existing layer may be recovered; two or more must come off. Winter Park amends the reroofing provision to read: "New roof coverings shall not be installed without first removing all existing layers of roof coverings where any of the following conditions exist: 1. Where the existing roof or roof covering is water-soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing. 2. Where the existing roof covering is wood shake, slate, clay, cement or asbestos-cement tile. 3. Where the existing roof has two or more than one application of any type of roof covering." The third condition is the operative one for an ordinary asphalt reroof.

Winter Park sets its own minimum sheathing thickness, adding a subsection that reads: "Wood Structural Panel Sheathing Thickness. A minimum of 5/8 inch plywood, particle board or wafer wood shall be used on roof rafters or roof trusses spaced 24 inches on center in any snow load area. Wood structural panel roof sheathing shall be bonded by exterior glue."

11.2 percent combined, among the highest in Colorado: 2.9 percent state, 1.30 percent Grand County and 7.0 percent Town of Winter Park. The Town is home rule and self-collecting, and states its own rate as "7.0%, comprised of 4% General Sales Tax, 1% Supplemental Sales Tax, and 2% Transit & Trails Sales Tax."
